Hi all,
I have posted before, last year I was battling with some Chinese batteries which were supposed to talk to my growatt inverter, however, I was defeated and ended up buying 2 x seplos 10e BMS, one is 200a other is 100a, only reason I didn't buy the same is I picked up the 200a cheap from eBay.
Anyway, I successfully swapped out and the growatt inverter picked up the batteries successfully.
However, I've literally installed BMS, connected and that's it.
Are there any settings I should change in the BMS.
For example, it seems by batteries are throttles at 3kw hr discharge.
Also it's 9 degrees outside now and it seems to have dropped to 0.25 kwh discharge with 40% soc showing. The BMS is showing a low pressure alarm.
Also the soc seems to jump, earlier when charging from panels it jumped from 80% to 90% almost immediately.
Similarly, though current Soc is 40 ish % I must be close to the total amount of kw/hr it can discharge. Last night it did similar thing, throttled to 0.25 discharge and then the soc slumped to 1%.
Almost feels like the soc is not calibrated with the cells?
Any settings I should change or advice welcome.
